For the Lake Wendouree Residence, the architectural design is significantly influenced by the existing

Firstly, environmental conditions including the proximity to the Lake presented complications in regards to the soils bearing capacity, being classified by the geotechnical engineer as a Class P (problem site).

In terms of architectural form, the roof profile is a clear homage to the surrounding boat houses. The slanting angles blurs the distinction between wall and ceiling through its variation of slopes.

increase spanning capacities, allowing internal spaces to be maximised.

The first floor’s vertical supports include additional lightweight components as less load bearing support is necessary, resulting in a

combination of steel and structural timber including kiln-dried hardwood. Similarly, cranked steel beams and roof truss systems allow an explo-

ration of form in regards to the roof, creating an intriguing variation of sloped planes. The kinked steel member acts as a column and beam, mapping the profile of the roof.

The same level of consideration is taken in regards to fittings and furniture. Elements including the floating kitchen bench and living

room shelving are established in this step through their required steel supports. This case study provides an excellent example of innovative architectural design that is seamlessly supported through a highly technical method of construction.

How do the internal partitions organise the life inside the building?

1. TIMBER STUD WALLS

FIXED

Internal partitions aid in defining functionality of spaces as well as influencing experience of occupancy. From entering the house, fixed partitions

90 x 45 non-load bearing MGP10 Pine

including brick walls and non-load bearing timber stud walls not only guide the occupant towards connecting spaces but also define specific rooms based on program. For example the stud wall that divides the kitchen and hallway provides a separation of functionality, as well as formulating a circulation threshold. This wall does not completely disconnect the two spaces but rather provides a distinction of functionality. Additionally the stairs

es, whereas the ground floor promotes a more public, social space through its increased open plan and communal function. Variations of internal cladding also organise program through further establishment of space, in particular the dining area’s timber finish clearly defines a boundary when entering that gives its own unique qualitative experience. In addition the various roofing profiles provide a similar distinction, almost sectioning the house into separate forms.

For the roof structure, components including the klip-lok roof sheeting, capping, flashing and downpipes are coloured to match the exterior zinc cladding, a clear attempt to camouflage these elements. Similarly the the box gutter is also concealed by the parapet eliminating any

to further emphasise the external materiality of claddings. The timber and zinc exterior is blatantly obvious, however it might be less so if these environmental protections were included. Another form of environmental protection to reduce solar heat gain is the timber screening on the west facade. This component is clearly portrayed and recognisable in the buildings elevation.

The mechanical and electrical systems are compositionally ‘zoned.’ While the internal HCAC systems for each floors are placed internally, the east perimeter provides a concealed location for the bore pump, AC condenser, WCOM, hot water boiler, booster, pump and meter board. By being located on the East boundary, minimum solar heat is gained allowing efficiency of mechanics. The Timber stud framework and truss systems are beneficial for these services as they contain hollow space for services to run through.

Water supply: Rooms that require water supply including bathroom, laundry and kitchens are placed in close proximity to each other including being stacked vertically

to minimise the distance of piping. The kitchen is place centrally to wet areas. The plan is not dictated by maximising water supply efficiency but rather a contributing factor.

Electrical: The electrical system is controlled by the meter board which is located on the east exterior wall, suitably next to the entrance. The solar panels propped on

angled stands maximise solar energy through its north facing direction, this powers the solar hot water system.

HVAC: The HVAC system is divided based on servicing different levels. The Ground floor location is next to the dining room, providing a central location that is approxi-

mate to communal spaces to be heated/cooled. Additionally the first floor HVAC system is located above the upstairs bathroom. This location is beneficial for servicing bedrooms.

The double height voids could be considered a detriment to heating as it will rise, however this aspect is outweighed by architectural design. Hydronic heating is also located in the slab and upstairs bathroom. However this form of heating takes time to heat up, therefore hydronic panels have been placed in bedroom for instant heating.

The majority of physical enclosures are illustrated through cladding and finishes mimicking the internal structure, providing a

representation of form. For example the boat house roof structure boasts its articulate form internally as well as externally. The exterior brick cladding facilitates the growth of climbing plants. These are also deciduous making the front facing facade a seasonal transformation. The extruding windows is a play on heaviness as aspects of the building appear to be floating, reinforced by cantilevering

forms evident throughout the house, but these elements are anchored to the ground level. However the use of vegetation could be seen as a contradiction to this aesthetic, as the intention of utilising brick was to express heaviness, however the plants mask this brick detaching the floating elements from the anchoring foundations.The rustic finish of external cladding including zinc is cohesive with the

HORIZONTAL ELEMENTS

timber cladding aesthetic. Additionally the identical internal and external timber cladding distorts the distinction between outside/inside, blurring the boundary. Internally the floor finish provides a distinction of functionality and space. Materials such as tiles, carpet and timber flooring can be used to determine the spaces program.
